Import Tips

• Provide chemical analysis confirming NbO2 composition to distinguish from mixed oxides excluded by Chapter notes

• Label with CAS number (12035-37-3) and hazard info for DOT compliance during import

• Avoid pitfall of classifying as artificial graphite mixtures if carbon-doped (heading 3801)
